CROSS REFERENCE TO RELATED APPLICATION

This application claims the benefit of priority to U.S. Provisional Application No. 62/376,513, filed on Aug. 18, 2016, which is herein incorporated by reference.

BACKGROUND

The current standard of in-flight data recording is limited to a manual process with pen and paper, as in international flight logs, or with pre-configured reports operating on specific triggers and storing data identified for collection in a set location. These methods are not convenient, robust, or conducive to real-time configuration.

In many existing avionics systems, recording of data is a predefined and automatic function that cannot be modified by an operator before, during, or after flight. In addition, current data recording methods are tied to an aircraft configuration and cannot be changed in real-time.

As such, a method to enable real-time configuration of data recording from both certified and non-certified devices, at any point in time, is needed.

SUMMARY

A system and method for dynamically recording vehicle data are provided. The system comprises an electronic unit onboard a vehicle, a data recording function hosted in the electronic unit, and one or more electronic data producers in operative communication with the data recording function. The data recording function is operative to receive a request specifying data parameters that at least include an identified electronic data set to record, a duration for the data recording, and a destination for the data recording. The data recording function is also operative to process the request based on the data parameters to produce a set of real time recorded data from the one or more electronic data producers, and to send the set of recorded data to a data storage location based on the destination in the request.

DETAILED DESCRIPTION

In the following detailed description, embodiments are described in sufficient detail to enable those skilled in the art to practice the invention. It is to be understood that other embodiments may be utilized without departing from the scope of the invention. The following detailed description is, therefore, not to be taken in a limiting sense.

A system and method for dynamically recording vehicle data with a data recording function are provided. The data recording function expands vehicle data recording potential to the super-set of vehicle data available on a vehicle data bus. The data recording function is implemented using a software protocol to configure data selection and file storage locations, both internal and external, in real time. The present approach allows pilots or third parties to use certified or non-certified devices to configure recorded content on-demand, and to provide a functional control to start, stop, and select storage locations for recorded data. In addition, the present approach provides for the ability to dynamically change vehicle data recording parameters in real time, and the ability to save the recorded data to any addressable location.

The data recording function has the technical benefit of alleviating manual effort for operators such as pilots, in terms of the flight logging process, and also provides a method of achieving on-demand data storage and portability for future use cases. The data recording function also allows for growth of future functionality by allowing access to all data on a given vehicle data bus.

The present approach provides for real-time recording of vehicle data upon an operator triggering a start and stop recording command. The data recording function can be implemented in various systems that allow an operator to start and stop a data recording based upon one or more user defined parameters. This functionality can be provided via a portable computing device such as a tablet (e.g., iPad), smart phone, electronic flight bag (EFB), or other input device (either external or as part of avionics, for example). In other embodiments, the data recording function can be implemented into various aircraft systems, such as a flight management system (FMS), and can be accessible to a pilot via flight pages on a cockpit screen.

In a method of operation for the data recording function, an application (which may be running on a tablet, EFB, avionics system, ground system, the cloud, etc.), sends a request to the data recording function specifying what data to record, for what duration, and to which file location (among other parameters). The data recording function, resident in a vehicle system, processes the request and consumes the vehicle data per the details of the request (start time, stop time, parameters to record, etc.) from a vehicle data bus. The data recording function then sends the recorded data to a file storage location as indicated in the request.

The file storage locations can be any internet protocol (IP) addressable location accessible to the data recording function, such as onboard storage, handheld storage, ground based storage, cloud storage, and the like. In addition, multiple application requests can be sent and processed by the data recording function at any given time.

Further details of the present system and method are described hereafter with reference to the drawings.

A mobile device 160 is configured for wireless communication with file server 122, such as through a Wi-Fi connection on an aircraft.

During operation of system 100, a DRF application on mobile device 160 sends a request to DRF 112 through LAN management unit 120. The request specifies what data to record, for what duration, and to which file location (among other parameters). The DRF 112 processes the request and consumes the data per the details of the request (e.g., start time, stop time, parameters to record, etc.) from bus 150. The DRF 112 sends the requested data to a data storage location supported by file server 122 as indicated in the request, such as by file transfer protocol (FTP) or other conventional methods. The data storage locations can be any IP addressable location accessible to DRF 112, such as onboard storage, handheld storage, ground storage, cloud storage, or the like. In addition, multiple application requests can be sent to DRF 112 for processing at any given time.

A DRF 212 resides in avionics unit 210, and a file server 222 resides in LAN management unit 220. The avionics data producers 240 are operative to send avionics data to DRF 212 such as through avionics bus 250. The DRF 212 is in operative communication with file server 222, such as through avionics LAN 230. As shown in FIG. 2, a cockpit display unit 254 is in operative communication with DRF 212, such as through avionics bus 250.

During operation of system 200, a DRF application in cockpit display unit 254 sends a request to DRF 212. The request specifies, for example, what data to record, for what duration, and to which file location. The DRF 212 processes the request and consumes the avionics data per the details of the request from avionics bus 250. The DRF 212 sends the requested data to a data storage location supported by file server 222, such as by FTP or other conventional methods.

A DRF 312 resides in avionics unit 310. A satellite communications (SATCOM) unit 324 onboard the aircraft is coupled to LAN management unit 320. The avionics data producers 340 are operative to send avionics data to DRF 312 such as through avionics bus 350. The DRF 312 is in operative communication with SATCOM unit 324 such as through avionics LAN 330. In addition, a ground station 360, such as an airline operation center, is in operative communication with SATCOM unit 324.

During operation of system 300, a DRF application at ground station 360 sends a ground initiated request to DRF 312 through SATCOM unit 324. The request specifies, for example, what data to record, for what duration, and to which file location. The DRF 312 processes the request and consumes the avionics data per the details of the request from avionics bus 350. The DRF 312 then sends the requested data through SATCOM unit 324 to a ground based file storage location.

FIG. 4 is a software flow diagram illustrating an exemplary operational method 400 for the data recording function, according to one embodiment. At a start point, a new or updated request is generated (block 410) and is sent to the data recording function (DRF) (block 412). A superset of vehicle bus data (block 414) is available to be sent to the DRF during a main process. The DRF processes the request information, which can be destination information for the data (block 416), a start/stop command (block 418), an identified data set such as an electronic data set (block 420), and a commanded duration (block 422). The destination information (from block 416) is sent to a transmit to destination module (block 440), which operatively communicates with a data storage location (block 450).

From the start/stop command (block 418), a determination is made whether a start command is given (block 424). If yes, a start clock module is initiated (block 426). A collect data subset module (block 428) collects the data after the start command based on the identified data set (from block 420), and sends the collected data subset to the transmit to destination module (block 440), which in turn sends the collected data subset to the data storage location (block 450).

After the start clock module is initiated (at block 426), a determination is made whether the commanded duration is exceeded (block 430). If not, the collect data subset module (block 428) continues to operate. If the duration is exceeded, or an externally defined stop condition occurs (block 432), a stop collection end point is reached (block 434). In addition, if a start command was not given (at block 424), the stop collection end point (block 434) is also reached.

A computer or processor used in the present system and method can be implemented using software, firmware, hardware, or any appropriate combination thereof, as known to one of skill in the art. These may be supplemented by, or incorporated in, specially-designed application-specific integrated circuits (ASICs) or field programmable gate arrays (FPGAs). The computer or processor can also include functions with software programs, firmware, or other computer readable instructions for carrying out various process tasks, calculations, and control functions used in the present method and system.
